' FOOD CHOPPER Filed July 16, 1929 Patented sept 23, 1930 MiGHAEL A. ROLLMAN, or MoUNrJoY; PENNSYLVANIA noon cnorrnn f Application filed July 16, 1sa.',. sem No. 378,646.,

I This invention relates to that type of foodchopper in which the cutting-and-forcing screw is mounted in a horizontal, internallyribbed cylinder and is adapted to cut or chop meat fed into the cylinder through va hopper mounted on its upper side and force the chopped meat through a perforated cutting-disk; at the exit-end of thecylinder, means being provided whereby the'device is 1?- adapted to be detachably clamped to the edge of a table; and the object of the present invention is to simplify and improve the construction of the combined hopper and cylinder in such mannerthat it may be more inexpensively produced and will be a neater and more sightly device when completed, as 'more fully hereinafter set forth.

T In the drawing annexed.

" Fig. 1 is a side elevation of a food-chopper made in accordance with my invention, the

screw and other working parts being omitted; 1 Fig. 2 is a vertical sectional view on the 7 line 22 of Fig. 1;

Fig. '3 is a horizontal sectional view on the line 33 of Fig. 1;

Figs. 4 and 5 are detail- Views of aslight modification. Referring to the drawing annexed by reference numerals, designates a standard provided at its lower end with the usual table-clamping device, being cast integral, at its upper end, with one-half of a combined cylinder and hopper, the two halves of the cylinder being numbered 11 and the two halves of the :hopperbeing numbered 12, the line of division beingvertical through the center of the hopper and the cylinder. As stated, one of these halves is cast integral with the standard, while the other half is cast as a separate piece.

The cylinder 11 is provided internally with the usual spiral rib or ribs and at each end with an annular bead 13. In the usual construction, these two halves of the cylinder are bolted or riveted together, the bolts or rivets being passed through lugs cast on the edges of the cylinder halves. This prior construction renders it difficult to properly tin the assembled parts, tinning being essential to'render the device rustproofand also for the purpose offilling and closing the ]Oints between the edges of the cylinder and the edges of the hopper sections.

In my present construction, I spinon each bead a sheet-metal band 14, the band at the exit-end of the cylinder being provided with a disk portion 15 which is provided with the usual cutter-opening 16 and the usual central opening 17 for the shaft of the screw, which latter is not illustrated, as'it is ofjthe usual I construction. The sheet-metalring at the rear end of the cylinder is spun tightly against the .rear end and has an annular flange 18 which extends into the cylinder and is pressed tightly against the interior face thereof. An outerfiange 19hugs the outer edge of the bead13 and extends inwardly upon the inner face thereof at 20. At the exitfend of the cylinder, a similar ring is spun on the head 13, this ring being also provided with an overhangingrib 20, but, insteadof the internal gripping-flange 18, this front ring is formed integral with the front cutting-disk 15. By thus spinning the sheet metal rings onto each end of the verticallydivided 'cylinder-and-hopper, theparts are clamped together, i hard contact, so that, when the body of the food-chopper is tinned in the usual manner, thewhole will become virtually a unitary structure, or practically the same as tho it were cast in a single piece. The tin seals all the joints much more effectively than is the case where the two halves of the hopper and cylinder are fastened together by bolting or riveting, since in this latter case it is difficult to get tin to enter all the crevices. It has long been known that the most desirable way to make the cylinder-and-hopper is to cast the same in a single piece, together with the standard, but this has been such a costly proposition that, in order to bring down the cost of manufacture to a point where competition in the market is possible, manufactures have been compelled to cast the structure in two parts and, as stated, rivet or boltthem together, and this notwithstanding the fact sults in a bad tinning job.

with their edgesin tight In the modification shown in Figs. 4 and5, the clamp-ring is constructed the same as shown at the forward end of Fig; 3 with the exception that, instead of having the over- 5 hanging part 20 extend entirely around the bead, it is in the form of two or more lugs 20* which are bent inwardly against the rear face of the bead 13 in the same manner as the annular continuous flange 20. What I claim as new is: v 1. A food-chopper emb dying a cylinder and a hopper cast in two halves and having their edges inabutting relation, the cylinder I being provided at each end with an outwardly-extending annular bead, and a sheet-metalring spun aroundeach bead to thereby peri manently and solidly clamp the twohalves to- 'gether, i

'2. A food-chopper embodying acylinder and a hopper castin two halves and having their edges in abutting'rela'tion, the cvlinder being provided ateach' end with an outwardlyextending annular bead, and a sheet-metal, ringspunaround each bead to thereby perina- 116111313 and solidly clamp the two halves together,the sheet-metal ring at the forward end of thecylinder having an annular flange entering the cylinder and contacting solidly with'the inner face of the cylinder and also with an extension clamping against the rear face of the bead. i r f 3. A food chopper embodying a cylinder and a hopper cast intWo halves and having their edges in abutting relation,-the cylinder 5W3; being provided at each end withan outwardly-extendinp'annular bead, and a sheet-metal ring spun around each bead to thereby permanently and solidly clamp the two halves together, the ring at the forward, exit end 0f the cylinder being formed integral with a perforated cutter-disk and having an extension bent over upon it so, as to grip the forward face of the bead. p
